The LAN 4 system is a keyboard based system with a vandal-proof digital combination which, by entering a PIN, allows one or two automation systems or any other device installed up to 300 m away from the decoder to be operated.
The keypads are easy to install either indoor or outdoor. With PIN up to 8 digit long. In case of keyboard tampering and after 25 unsuccessful PIN attempts with 120 s, the keyboard is locked and, for 120 s, it will no longer recognise any PIN, not produce any sound signals. After this time is elapsed, the keyboard will automatically go back to the waiting and PIN entering status.
